drm-intel-next-2018-09-06-1:
UAPI Changes:
- GGTT coherency GETPARAM: GGTT has turned out to be non-coherent for some
  platforms, which we've failed to communicate to userspace so far. SNA was
  modified to do extra flushing on non-coherent GGTT access, while Mesa will
  mitigate by always requiring WC mapping (which is non-coherent anyway).
- Neuter Resource Streamer uAPI: There never really were users for the feature,
  so neuter it while keeping the interface bits for compatibility. This is a
  long due item from past.

Cross-subsystem Changes:
- Backmerge of branch drm-next-4.19 for DP_DPCD_REV_14 changes

Core Changes:
- None

- Do a full device reset after being wedged (Chris)
- Keep forcewake counts over reset (in case of debugfs user) (Imre, Chris)
- Avoid false-positive errors from power wells during init (Imre)
- Reset engines forcibly in exchange of declaring whole device wedged (Mika)
- Reduce context HW ID lifetime in preparation for Icelake (Chris)
